We present an efficient method for monitoring woody (i.e., evergreen) and herbaceous ephemeral) vegetation in Mediterranean forests at a sub pixel scale from Normalized Difference Vegetation Index (NDVI) time series derived the Moderate Resolution Imaging Spectroradiometer (MODIS). The is based on distinct development periods of those components. In dry season, absent or completely forests. Thus mean NDVI season was attributed to (NDVIW). A constant value assumed soil background during this...
Abstract The December 2010 forest fire on Mount Carmel – the largest recorded in Israel burned about 2500 ha of Mediterranean forest. We documented immediate and short‐term changes vegetation following this fire. Relative cover plant species richness were sampled five sites spring 2009 2010, prior to fire, re‐sampled 2011 2012. number recurrent fires (between 0 3) time intervals between for each site. observed a strong decrease total cover, associated with reduction relative woody...
The wildland-urban interface (WUI)—the area where wildland vegetation and urban buildings intermix—is at a greater risk of fire occurrence because extensive human activity in that area. Although satellite remote sensing has become major tool for assessing damage wildlands, it is unsuitable WUI monitoring due to the low spatial resolution images from satellites provide frequent information which relevant timely WUI. Here, we take advantage (i.e., ca. daily), high-spatial-resolution (3 m)...
Variations in forest fires regime affect: (1) the natural patterns of community structure and vegetation; (2) physico-chemical properties soils consequently (3) runoff, erosion sediment yield. In recent decades Mediterranean ecosystem Mount Carmel, north-western Israel, is subjected to an increasing number fires, thus, objectives study were evaluate long-term effects single recurrent on soil water repellency (WR) organic matter (OM) content. Water was studied by applying drop penetration...
Massive destruction of carbonate rocks occurred on the slopes Mount Carmel during severe wildfire in 2010. The bedrock surfaces exhibited extensive exfoliation into flakes and spalls covering up to 80–100% exposed rocks; detached boulders were totally fractured or disintegrated. fire affected six units – various types chalk, limestone dolomite. burned show a consistent tendency towards flatness, all lithologies. extent physical disruption depends rock composition: most response was found...
Background and Aims Speciation is often described as a continuous dynamic process, expressed by different magnitudes of reproductive isolation (RI) among groups in levels divergence. Studying intraspecific partial RI can shed light on mechanisms underlying processes population Intraspecific divergence be driven spatially stochastic accumulation genetic differences following reduced gene flow, resulting increased with geographical distance, or local adaptation, environmental difference....
On 24 November 2016, extreme hot and dry weather led to more than 1000 fires in Israel. One of the largest (120ha) occurred city Haifa. The fire began on slopes north-eastern part wildland–urban interface (WUI) spread into city, moving westward owing strong wind gusts. Although private houses open lands villages Israel have previously been affected by fires, this was first ‘urban fire’ In order determine best management strategy for various types burned areas, an ‘identity card’ prepared...
No records exist in the scientific literature about lightning fires eastern Mediterranean (EM). Although thunderstorms are frequent winter, if spontaneous fire is ignited, it will immediately be extinguished by rain. occur summer, and therefore no favourable weather conditions for natural ignitions exist. In October 2014, synoptic over EM comprised a Red Sea Trough (RST) with an easterly axis (a less version of this system). A convective storm, accompanied intense local rains developed...
For the past decade, Twitter has become a robust platform for distributing messages (tweets) among numerous subscribers worldwide. During and around occurrence of natural hazards, tweet volumes increase significantly. While is used near real-time alerts, processes extracting reported damage from tweets resolving their geographical spread in high resolution are still under development. In this study we examine spatio-temporal distribution associated with November 2016 fire, which lasted Haifa...
During the last decade, Twitter has become a robust platform for distributing messages (tweets) among numerous subscribers worldwide. and around occurrence of natural hazards, tweets increase significantly. While is used near real-time alerts, processes extracting reported damage from resolving their geographical spread in high resolution are still under development. In this study we attempt to examine what was spatio-temporal distribution associated with November 2016 fire Haifa (Isreal)....
